Some sources show or imply that Gilbert was son of Andrew but TSP reports that the Sir William who married Janet Dunbar was great-great-grandson of the John who married Mariotta de Cheyne which, by reference to the dates, seems more likely. It is possible that the father of the next Gilbert was also called Gilbert and that one or two of the ladies reported below as wives of Gilbert, 3rd of Inverugie, were in fact his mother. It is not known who of those shown as Gilbert's wives was mother of whom.
